General
-- The 3 inch couplings are supplied with a choice of seal materials and with optional selectivity to suit a
particular application or customer requirement. The coupling build standard is indicated by the part
number suffix letters:
1st suffix; V or N = seal material
2nd suffix; SA to SW (excepting SI and SO) = selectivity (optional)

WARNING: DO NOT HANDLE O-RING SEALS IF THEIR MATERIAL APPEARS CHARRED, GUMMY
OR STICKY. USE TWEEZERS AND WEAR NEOPRENE OR PVC GLOVES. DO NOT
TOUCH ADJACENT PARTS WITH UNPROTECTED HANDS. NEUTRALIZE ADJACENT
PARTS WITH A SOLUTION OF CALCIUM HYDROXIDE. IF THE DEGRADED MATERIAL
OR ADJACENT PARTS TOUCH THE SKIN, DO NOT WASH OFF WITH WATER, SEEK
IMMEDIATE MEDICAL AID FOR POSSIBLE CONTAMINATION WITH HYDROFLUORIC ACID.
HYDROFLUORIC ACID IN CONTACT WITH SKIN HAS DELAYED SYMPTOMS OF
CONTAMINATION. IT IS EXTREMELY TOXIC.
User Instructions
-- Cleanliness is essential for trouble-free operation of the couplings. Always ensure that blanking caps
are installed when units are disconnected.
-- Periodically examine couplings for contamination, evidence of leakage and damage. Clean couplings,
as necessary, with lint-free cloth or a soft bristle brush moistened with a suitable cleaning agent; pay
particular attention to hose unit and tank unit seal recesses.
Repair
-- Repair of couplings is by replacement of faulty seals and worn or damaged components. Repair
procedures are straightforward and no special tools are required. Refer to exploded views and the
following outline procedures for guidance.
Dismantling notes
-- Hose units: Separate hose connector (16) from cam (22) by removing plug (14) and rotating hose
connector to release bearings (15); collect cam rollers (6). Remove cap nuts and spring washers and
the three bayonet rollers (3) from the cam. Remove spanner ring (9) and valve components from the
cam. Remove pin (7) to separate valve (8 from connecting rod (12).
-- Tank units: The valve in the tank unit is spring loaded and care must be taken to avoid injury when
removing the valve guide. Hold the valve guide (29) in place and carefully remove the circlip (28).
Allow the spring to expand slowly, and remove the valve guide, spring (30) and valve assembly (32).
Cleaning and Inspection
-- Clean all metal components using lint-free cloth moistened with a suitable non-toxic cleaning fluid.
Ensure that residues of seal material are removed from O-ring seal grooves and from all sealing faces;
use fine grade wire wool, if necessary.
-- Examine all parts for damage, evidence of wear and condition of surface protection (Fluoron coated
components). Discard unserviceable components together with all used seals and pins; refer to
spares list for replacement parts.
Assembling
-- Assemble units in the reverse order of dismantling and note the following:
-- Exercise care when installing O-ring seals in ‘dovetail’ grooves; use a suitable lubricant if necessary,
and wipe off any excess after assembly.
-- When installing the spanner ring in the hose unit, ensure that the stops are positioned under the
bayonet roller locations.
-- Ensure that the handles are correctly orientated on the hose unit.
-- The Nyloc nut securing the seal support plate in the tank unit blanking cap must be slackened
approximately one turn to allow the seal plate to rotate in the cap.
Testing
-- Couple the repair unit to a serviceable hose or tank unit as appropriate and check for correct
operation of valve actuating and bayonet locking mechanism. Couple and uncouple unit(s) several
times.
